This is a graphical curve that appears to be normal in height and shape, but is not aligned with a typical display. This can be due to a tilted optic nerve or altered anatomy that would not be considered glaucomatous in nature. The corollary of this finding is that any statistically anomalous areas (i.e. those indicated with the background colour yellow, red or white) would not be considered abnormal if the curve were simply moved, or shifted, into a more normal position. In this case, all of the curve would fall within the green (normal) spectrum.
